(II) the height width ratio of dry-type transformer pier installed on the ground is generally .m, and a guardrail of no less than m shall be installed around it, and a warning sign shall be hung at a prominent position.Note: in the whole process of safety patrol inspection,KaramataWorking principle of power transformer, the on-site operation and maintenance management staff must use temperature tester or thermal imager to carry out purposeful inspection on the transformer itself, terminal block and other accessories; The sound during the operation of the transformer is a symmetrical current sound. If the sound is found to be abnormal, significantly expanded,KaramataModel of electronic transformer, or there is local sound, the cause shall be found immediately and certain effective measures shall be taken. If necessary, the load can be reduced or the operation of the transformer can be stopped.Karamata,Transformer manufacturerFor the installation of lightning rod, it is very easy to damage the relay protection inside and outside of dry-type transformer by lightning. If it is a serious situation, it is very easy to cause fire accidents, power failure, damage to machinery and equipment, etc.Trogil,Power transformer manufacturerThe raw materials of Fushi blue can be used for bonding, so that the overall oil leakage of the connector can be greatly controlled; If the actual operation is convenient, the metal shell can also be bonded at the same time to achieve the purpose of leakage treatment.When we apply oil immersed transformer, we all know that it works with the help of oil. What if the oil immersed transformer is on fire? What countermeasures should we do?

Difference between dry-type transformer and oil immersed transformer:Power transformer is indispensable for power stations and substations but we must pay attention to many problems in the whole process of applying power transformer.Then clamp the branch pipe with your thumb, clearly put forward the glass test tube, carry out it twice,KaramataAdvantages of dry-type transformer, and then draw the oil sample.Trustworthy,When sampling from a small and medium-sized power transformer without a discharge pipe (or oil sample suspension plate), it can be in a power transformer such as a glass test tube when it is not in operation to extract the oil sample at the bottom, the electric flow will leak into the earth along the installed grounding wires, so as to achieve the purpose of safety, the voltage caused by the zero line can not be ignored. As a countermeasure to maintain life safety, it is more and more unreliable. Ground wire (PE): it is not used as a working circuit, but only as a maintenance line. Use the affirmation of the earth & ldquo; ” Voltage. When the machine and equipment casing is electrified, the current will be quickly grounded. Even if there is a lead for the PE line, it will be grounded from the surrounding grounding body.

(I) the distance between the external contour of kV and below dry-type transformer and the surrounding guardrail or courtyard wall shall take into account the convenience of transportation and repair of dry-type transformer, and the distance shall not be less than m; At the angle with actual operation, a spacing of more than m shall be reserved; If metal fence is selected, the metal fence shall be grounded and a warning sign shall be hung at a prominent position.Packaging strategy,Before no-load impact closing, the pose period of overcurrent protection shall be set to zero, and the data signal circuit of steam vehicle relay shall be temporarily connected to the pull-in circuit.Power saving analysis of transformers has always been based on whether the utilization rate of transformer capacity is less than a certain standard value. Whether transformers are environmental protection and energy saving specifications. In fact, sometimes such specifications are not saving electromagnetic energy but consuming electromagnetic energy.For kVA power engineering transformer, plastic parts are selected in the middle of iron core, clamp and electromagnetic coil to keep the electromagnetic coil in a stable clamping state to reduce noise.Karamata,The insulating layer shaft and the connecting articles between the bell jar and the core shall be removed. If it is a hanging bell inspection, the oil shall be pumped into the bottom of the bell jar before the bell jar can be removed.(I) the distance between the external contour of kV and below dry-type transformer and the surrounding guardrail or courtyard wall shall take into account the convenience of transportation and repair of dry-type transformer, and the distance shall not be less than m; At the angle with actual operation, a spacing of more than m shall be reserved; If metal fence is selected, the metal fence shall be grounded and a warning sign shall be hung at a prominent position.The representative mode of connection group of dry-type transformer is: English capital letters indicate the wiring on the primary side (or primary side), and English letters indicate the wiring on the secondary side (or secondary side). Y (or y) is star wiring and D (or D) is triangular wiring.
